[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a self-propelled transfer conveyor device which is amphibious and can be used for carrying sediment during landfill work.

[Conventional technology]

2. Description of the Related Art Conventionally, a self-propelled transfer type conveyor or a shiftable conveyor in which a plurality of conveyor supporting frames are connected has been used in a face or a landfill such as a soil collecting yard.

Figure 7 shows an example of a self-propelled relocation system. In the figure (01a)
(01b) (01c) are three conveyor support frames, (02
a) is a crawler traveling machine that supports the rear and front ends of the conveyor supporting frames (01a) and (01c), and (02b) is a similar crawler traveling machine that supports the conveyor supporting frame at the middle of the conveyor supporting frame, ( 03 is a conveyor extended and laid on the conveyor support frames (01a) (01b) (01c) and the crawler traveling machine (02b), (04) is a loading hopper provided at the rear end of the conveyor, and (05) is It is a payout tripper that runs on a conveyor.

When it is put into the hopper (04), it is sent to the left side of the figure by the conveyor (03), and the earth and sand is discharged to the landfill through the right end tripper (05). To move the entire conveyor, move the crawler traveling machines (02) all together under the conditions shown in the figure, and the entire conveyor will move to the front side of the figure. Similarly, align the crawler traveling machines (02) in the same direction. It can be relocated by moving in any direction by changing and running all at once. FIG. 8 shows a case where the above-described conventional self-propelled transfer conveyor device is used at a landfill site.
(06) is a sediment transport barge, (07) is an unloader for excavation,
(08) is a spreader that receives soil from the tripper (05) at the end of the conveyor and discards it to the landfill (09), and (010) is a revetment built around the landfill area. In addition, Fig. 9 shows that multiple conveyor barges (011) are continuously arranged on the surface of the landfill site, and the soil discharged by the unloader (07) is sent in sequence by the conveyor barge (011) ... and the shipboard spreader (08) at the tip is used. The conventional method of discarding soil is shown.

[Problems to be solved by the device]

The conveyor barge method shown in FIG. 9 uses independent conveyor barges (011) connected to each other, which increases the height of the conveyor, and each barge swings due to wind and waves.
Compared with the above-ground conveyor shown in Fig. 8, it has a drawback that the work is difficult to stabilize. On the other hand, in landfill construction close to land, the bottom of the water generally has a lot of sedimentary soil such as sludge, and if the landfill sand is directly input, soft sedimentary soil will float up and will be pushed out of or mixed with the landfill soil. There is a problem that the ground that has been removed weakens. In order to prevent this, when the seabed is sedimentary soil, after constructing a revetment (010), as shown in Fig. 10, first, a good quality sand is spread on the sediment (012) to a thickness of about 1 m. Sand matte (013) The method is to bury the earth and sand (014) such as ordinary soil and construction soil on it. This sand matte (013) construction and the initial landfill from the sea side are carried out by using the conveyor barge system as shown in Fig. 9 or the spreader attached to the floating unloader for landing, and the landfill is completed. After that, there is an uneconomical need to use water conveyors, ground conveyors, and other types of equipment such as the use of ground conveyors as shown in FIG.

[Means for Solving the Problems]

The present invention has been proposed for the purpose of improving the above-mentioned conventional problems, and as an amphibious conveyor device, a plurality of conveyor support frames whose end portions are connected and extended and a plurality of conveyor support frames are run. A buoyant body in a frame between fulcrums in which the conveyor support frame engages with the traveling machine. The traveling machine has a vehicle body formed in a buoyant structure, and further comprises a water jet propelling machine that operates in the front-rear and left-right directions on the vehicle body, and a swivel base for supporting the conveyor support frame on the vehicle body.

[Action]

When the conveyor according to the present invention is installed on the ground, the earth and sand load applied on the conveyor is supported by being in contact with the ground from the conveyor support frame via a plurality of traveling machines. The unloaded unloader is continuously supplied into the receiving hopper of the conveyor,
Sediment is carried by the conveyor device, and the sand is dropped to the on-board hopper of the spreader via the tripper on the way, and the earth and sand is sprinkled to the landfill site through the on-board conveyor of the spreader.
When the spreader moves away from and moves in the longitudinal direction of the self-propelled transfer conveyor, the above-ground conveyor aligns the crawler traveling machine in the longitudinal direction of the conveyor, makes the crawler run in unison along the moving direction of the spreader, and receives the rear part of the conveyor. The length of the conveyor is adjusted by sending the hopper back to the rear to accommodate the change in the position of the spreader.

When the spreader changes its position laterally with respect to the conveyor, the above-ground conveyor moves the traveling machines in the circumferential direction in parallel so as to keep the end on the unloader side in the original position. The position change can be followed. Furthermore, the soil supply point can be changed and the device can be moved in parallel at the same speed.

Further, as the landfill progresses, the conveyor support frame and the traveling machine can be additionally connected to increase the conveyor length.

When installed above water, the above-mentioned ground conveyor can be directly drawn onto the water. The sediment load on the conveyor and the weight of the support frame are supported by the buoyancy of the buoyancy body provided in the support frame and the buoyancy structure of the main body of the traveling machine. The buoyancy of the buoyancy body keeps the stability and stability of the entire conveyor system.

Further, a tripper mounted on the conveyor can be used to carry out the sedimentation. When using a tripper on a conveyor, the landfill side of the conveyor can use a horizontal lower conveyor support frame similar to the delivery side.

The length of the conveyor can be adjusted by additionally connecting the conveyor-support frame, and the longitudinal movement of the conveyor and the lateral movement of the conveyor can be performed by driving the water jet of the traveling machine in the longitudinal direction or in the lateral direction. . A mooring line is used to hold the position of the conveyor support frame on the water.
